Grill ignites but then goes out after 10–20 minutes; temperature drops and smoke stops.

Safety first: After a flame-out, unplug the grill and allow it to cool before relighting. Unburned pellets may be present in the firepot.

Steps to address intermittent flame-out:

• Clean firepot and burn area: Remove grates and internals, then vacuum ash and debris from the firepot and surrounding area. Do this regularly (every few cooks).
• Check pellet quality: Use only dry, high-quality hardwood pellets. Discard any that are dusty, crumbly, or damp.
• Observe pellet feed: During a test cook, watch the firepot (from a safe distance) to ensure pellets are feeding at regular intervals. Long gaps can cause flame-out.
• Verify fan operation: Confirm that the combustion fan runs continuously during the cook. Weak or intermittent airflow can cause the fire to die.
• Inspect auger motor: If the motor stalls intermittently or makes unusual noises, replace it.

Note: If flame-outs persist after cleaning and verifying components, the controller's feed algorithm or power output may be faulty and the controller may need replacement.
